Essentials Fluids Drink LOTS of water or an electrolyte replacement drink Bring enough to last you the entire day or continuously refill your container Sunscreen or sun block Apply before you arrive at work Reapply throughout the day Wear the proper attire Light colored clothes reflect the sun and help to keep you cool Covering your skin will better protect against damaging UV light Wear a hat Better protects the sensitive skin of your ears, neck and face
Sun block Sun block is opaque and stronger than sunscreen Able to block a majority of the UVA/UVB rays and radiation from the sun, Sun block's ingredients do not break down rapidly in sunlight so it is unnecessary to reapply frequently. Sunscreen Sunscreen is more transparent once applied to the skin Also able to protect against UVA/UVB rays Sunscreen's ingredients break down at a faster rate once exposed to sunlight, allowing radiation to penetrate the skin. For sunscreen to be more effective frequent reapplication and a higher spf is recommended. Sun Protection Factor (SPF) The SPF of a sunscreen is a laboratory measurement of the effectiveness of sunscreen The higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes a sunburn).
Dehydration Thirst By the time your body tells you that you are thirsty you are already mildly dehydrated. Drinking water at this stage can prevent you from progressing to the more serious kinds of heat related illnesses. Heat cramps: Cramping in the abdomen, legs or arms The loss of water and salt from heavy sweating causes cramps. These cramps can be mild or very painful. Heat exhaustion Dizziness Headache Nausea
Heat Stroke or sun stroke Hot, red and dry skin Rapid, weak pulse Rapid, shallow breathing. Increase in body temperature –can reach as high as 105 o F. Vomiting. Confusion. Throbbing headache. Decreased alertness level or complete loss of consciousness. Seizures.
First Stage: Dehydration Easily curable with shade, rest and water May resume work activities after symptoms subside Second Stage: Muscle Cramps Easily curable with rest, massage and water May resume work activities after symptoms subside Third Stage: Heat exhaustion Moderately easy to cure with shade, rest and water May or may not be able to resume work Fourth Stage: Heat Stroke or Sun Stroke Life threatening-Call 9-1-1 immediately May not resume work
For Heat Cramps 1.Stop activity and rest. 2. If the person is fully awake and alert, have him or her drink small amounts of cool water or a commercial sports drink. 3.Gently stretch the cramped muscle and hold the stretch for about 20 seconds, then gently massage the muscle. 4.Repeat these steps if necessary. 5.If the victim has no other signals of heat-related illness, the person may resume activity after the cramps stop.
For Heat Exhaustion: 1.Get the person to a cooler place and have him or her rest in a comfortable position. 2.If the person is fully awake and alert, give a half glass of cool water every 15 minutes. Do not let him or her drink too quickly. Do not give liquids with alcohol or caffeine in them, as they can make conditions worse. 3.Remove or loosen tight clothing and apply cool, wet cloths such as towels or wet sheets. 4.Get the person into an air conditioned space if possible. 5.Call 9-1-1 or the local emergency number if the person refuses water, vomits or loses consciousness.
For Heat Stroke: Heat stroke is a life-threatening situation! Help is needed fast. 1.Call 9-1-1immediately 2.Move the person to a cooler place. 3.Quickly cool the body using any means available, including cool water and ice. If you have ice packs or cold packs, wrap them in a cloth and place them on each of the victim's wrists and ankles, in the armpits and on the neck to cool the large blood vessels. 4. Wrap wet cloths around the body and place the person in front of a fan or air conditioner. 5.Watch for signals of breathing problems and make sure the airway is clear. 6.Keep the person conscious
